So after studying the schematic, I started looking for the 30A fuse that goes from the charger to the batteries. I found it mounted to one of the batteries. The fuse holder had actually melted. I replaced the fuse and holder and the charger started right up. I kept an eye on temperature of the new holder and the wires running to it. They get quite warm, but not enough to melt the new holder at this point. I am worried what made it so hot in the first place and am concerned it will happen again. We'll just have to wait and see.
